FLUID FOR PROMOTING COMBUSTION.

SPECIFICATION forming part of Letters Patent No. 700,888, dated May 27,1902.

Application filed December 28, 1901. Serial No. 87,556. (No specimens.)

T0 aZZ whom it may concern.-

Be it known that I, TIMOLEONE BATTISTINI, a subject of the King ofItaly, residing at Genoa, Italy, have invented a certain new and usefulFluid for Promoting Combustion, of which the following is aspecification.

The object of the present invention is to provide for the economiccombustion of fuel in such a way that its calorific or heating power ismaterially increased at a very small expenditure for time, labor, andmaterials, while at the same time the grate, fire-tubes, and other partsof the boiler and furnace are uninjured and the amount of smoke givenoif is materially diminished.

To these and other ends hereinafter set forth, the invention, statedingeneral terms, comprises a fluid intended for application to the fuelfor promoting combustion and which contains material adapted when heatedto yield oxygen, so as to consume thoroughly the volatile and otheringredients of the fuel, and also a retaining material for preventingthe escape of the volatile and other matters from the fuel, so that theycan be burned under the influence of the oxygen-yielding ma terial.

The fluid of the invention comprises a solution of one part of nitrateof sodium and two parts of carbonate of sodium, the said parts beingmeasured by weight. The solution may be made in water and is applied bysprinkling or otherwise bringing it into contact with the fuel, whichmay be either soft or hard coal or charcoal or other similar material.The fuel is permitted to dry before it is burned and after it has beentreated with the solution or fluid, as described. The purpose of thesodium nitrate, which when heated yields oxygen, is to supply oxygen foreffecting better combustion of the fuel than has heretofore beenattained, and the purpose of the sodium carbonate is to prevent theescape of combustible matters from the fuel, so that they are consumedby the oxygen given off in the manner described. The effect of thesolution is to materially increase the calorific power of the fuel, andthere is nothing given off that can in any way deleteriously affect thefurnace or other parts with which the products of combustion come intocontact. Of course the sodium carbonate and sodium nitrate may beseparately dissolved and separately applied, although it is usually moreconvenient to make them in one solution.

It will be obvious to those skilled in the art to which the inventionrelates that medi fications may be made in details without de partingfrom the spirit thereof.

Having thus described the nature and objects of the invention, what Iclaim as new, and desire to secure by Letters Patent, is

A fluid for promoting combustion which comprises a solution consistingof one part by weight of nitrate of sodium and two parts by weight ofcarbonate of sodium, substantially as specified.

In testimony whereof I have hereunto signed my name.

TIMOLEONE BATTISTINI.
